2.4L D5 · Remanufactured
Volvo 2.4 D5 (D5244T family) Bosch common-rail injector
D5244T, D5244T2, D5244T3
Hard starting when warm; uneven idle across the five cylinders; loss of power with rail-pressure faults; excess smoke on hard acceleration; diesel knock from one cylinder. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Injector back-leak beyond specification on high-mileage engines; nozzle wear causing over-fuelling on individual cylinders; injector seat sealing failure causing compression leakage (black tar around injector). Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Five-cylinder layout — compare leak-off volumes across all five injectors, not just the suspect one. Clean around the injector seats before removal to stop debris entering the bores. Check for carbonised sealing washers ('black death') and clean seats fully before refitting. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 0445110078 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is calibrated on a common-rail test bench against the manufacturer's specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data on file.
The 0445110078 trusted family covers 5 verified vehicle fitments across 1 makes: Volvo. Every fitment listed is registry-verified.
0445110078 cross-references 18 further OE numbers, including 0445110077, 0986435120, 30756063, 30777314, 31303259, 36051165, 8602669 and 8602699. Always match the reference etched on your failed unit's body.
